Fig. 2 is a detail side view partly in section of the front end of the apparatus; and

Fig-3 is a similar view of the rear or locomotive end of the same.

The apparatus consists essentially of a tube or barrel 10 extended forward from the locomotive 11 on the line of the track 12 in advance of the locomotive and supported by suitable trucks 13. preferably of light construction but of a weight suiiicient to maintain the same upon the track rails, the front end of the barrel being provided with an explosion chamber 14 for the reception of a cartridge 15. The discharge of said cartridge is effected by a firing pin 16 which is carried by a head 16a adapted for contact with the opposing head of the train approaching from the opposite direction and provided with a similar equipment as indicated in Fig. 1.

The barrel 10 is made insections which are united by couplings 10a, and it is supported upon the trucks 13 by rods 13a. The rods are connected to the trucks 13 as at 13b and to the couplings 10a as at 13". The head specification of Lettersratent.

Obviously the forwardly projecting apparatus will be more or less damagedV or mutilated by the contact thereof after the lsignal 185 has been given and before the trains can be brought to a stop, but the cost of such apparatus is negligible as compared with that of f the locomotivesl and train equipment, 'and' hence may readily be sacrificed in order to save the loss of the train equipment as well as to minimize the loss of life incident tothe Y destructive contact of the locomotive. i

The forwardly extending barrel of the apparatus will follow the curvature Vof the tracks, the same being ofsufiicient flexibility for this purpose, so Vthat the device will serve its purpose uponv curves aswell' as i l upon straight lines of tracks, the funnel 18 serves to permit of a certain angular movement of thenozzle 17 without disturbing the relations of the parts sufficiently to involve the Afailure of the projectile-traversing thev ported barrel 'adapted for projecting' in ad- Vance of a locomotive and provided at its forward end withv explosive means for discharging a projectile rearwardly through path said barrel, and a detonating apparatus carLv ried by the locomotive for actuation'by a projectile traversing the barrel. ,s l
